Patent GB-1336927-A (GB)
Title: Semiconductor circuits
IPC: G11C19/28
Filed: 1971-07-05
Abstract: 1336927 FET Bi-stable circuits WESTERN ELECTRIC CO Inc 5 July 1971 [9 July 1970] 31302/71 Heading H3T [Also in Division G4] First and second out-of-phase clock signals are applied over respective metallized conductors 25, 35 to all the register stages, each conductor 25, 35 serving alternately to supply its respective clock signal and provide a return path from the stages to ground. The stage shown comprises insulated gate field effect transistors of the 8 channel enhancement type. Transistors 20, 21 act as cross-coupling devices for transistors 16, 18, transistors 22, 23 and 32 act as loads and transistor 30 acts as an input device to which the output of the preceding stage is supplied. When phase II is at ground, transistor 30 conducts to render transistor 16 conducting if input 12 is near ground. When phase I subsequently falls to ground, transistors 20- 23 are enabled and conduction of transistor 16 increases because of the charge stored on its gate-source capacitance, and transistor 18 is disabled. The state of transistor 18 is transferred to the next stage when phase II again falls to ground, transistor 32 conducting at this time to replace load transistor 23 which is cutoff by phase I going positive.

Title: Improvements in or relating to steam generating and accumulator plant
IPC: F22G1/16
Filed: 1937-11-15
Abstract: 490,883. Heating steam boilers by steam ; steam regenerative accumulators. RUTHS INTERNATIONAL ACCUMULATORS, Ltd. Nov. 15, 1937, No. 31380. Convention date, Nov. 16, 1936. [Class 123 (ii)] High-pressure steam is generated by circulating water through a heat-exchanger 2 heated by relatively low-pressure steam superheated by electricity. Steam is drawn from a low-pressure steam distributer 4, Fig. 1, by a compressor or pump 3 and is circulated through an electrically heated superheater 1 and the heat-exchanger. Water in a boiler or storage chamber 5 may be circulated through the heat-exchanger by a pump 6. The superheated steam circulated through the heatexchanger 2, Fig. 2, is led into the water in a regenerator 9 from which is drawn and forced through the superheater 1 by a pump 3. A steam coil 10 cools the superheated steam between the heat-exchanger and the regenerator. The superheated steam may pass through a heating coil in the regenerator and returned to the steam circuit, and steam may be admitted to the heating circuit from the boiler or storage chamber. In place of an electric heater 1, the steam may be heated by an electrically driven circulation pump 6 of such a low efficiency that most of the electric energy is transformed directly into heat.

Title: A coin-controlled amusement machine
IPC: G07F17/38
Filed: 1932-11-09
Abstract: 408,365. Coin-freed game apparatus- MIDLAND COMPONENTS, Ltd., ALKIN, R. L., and MATT, H. A., Sterling Works, Spon Street, Coventry. Nov. 9, 1932, No. 31624. [Class 27.] Tivoli billiards and like games ; coin action, with stationary coin forming abutment.-In a coin-controlled amusement machine where balls can rest on supporting means 17, Fig. 2, in holes 13 in a playing board 10, a coin 23, Fig. 3, inserted in a shoot 21 drops to a curved seating 22 at the bottom of the shoot and rests against a pin 24 on an operating member 25 which, when pulled out, actuates the supports 17 to release the balls. The member 25 is connected by a pivoted link 26 to a pull rod 27 and, in the absence of a coin, is prevented from being fully pulled out after a slight movement by a second pin 28 thereon engaging a stationary catch 29. When a coin is present, the pin 24 rides up its periphery thereby raising the pin 28 above the catch 29. During the return of the member 25 by a spring 30, the pin 24 forces the coin down to a money-box, while the pin 28 rides up an incline 35 to the operative side of the catch 29. During the last part of its outward movement, a pin 33 on the member 25 actuates a lever 32 to move the support 17. The support is an apertured plate or false bottom the holes in which are normally out of register with the holes 13 in the board 10. When it is actuated to bring the holes into register, the released balls drop through to an inclined platform 19 with the lower end of which co-operates a platform 20 that can be raised to bring them into play. The platform 20 is connected by a lever 31 to the member 25, so that it is lowered, when the member is pulled out, and raised on its return. In order to prevent return of the member 25, should it be inadvertently released before actuating the support 17, a catch 39 thereon engages, during its outward movement, with the flat face 38 of a pivoted spring-controlled pawl 36.

Title: Memory
IPC: G11C14/00
Filed: 1976-07-29
Abstract: 1502058 Data store INTERNATIONAL BUSINESS MACHINES CORP 29 July 1976 [25 Aug 1975] 31672/76 Heading G4C A data store includes two arrays of cells 17; and 4, 5, with respective sets of word lines 18; and 24, 10, and with corresponding bit lines 20; 16 connected by switches 21, the arrangement being such that by selectively actuating the switches 21 and addressing the cells via the common bit and separate word lines a selected cell in either array may be read out through the corresponding one of a single set of sense amplifiers 11 connected to the bit lines of one of the arrays. The two arrays are a read/write and a read only array sharing common sense amplifiers and bit line decoders, the whole circuit being formed as an integrated circuit. Each read/write cell 4, 5 includes a transistor 7, 40 connecting a capacitor 6, 32 to a bit line, only one of which is shown. The read/write array is a split array whose halves are separated by sense amplifiers in the form of a latch 11 in each bit line. Each read only cell is formed by an operable or inoperable (the gate being omitted) FET, depending on whether a binary 1 or 0 is stored, connected between a potential V and a bit line 20, only one of which is shown. To write data a read/write cell is addressed by energizing an appropriate word line 10, 24 and raising or lowering the potential of the appropriate bit line 33 to V or ground depending on whether a binary 0 or 1 is to be stored. The corresponding voltage is written into the cell capacitor in the right hand half of the array, the voltages being reversed by the inverting latch for the left hand half, the inversion being repeated and therefore cancelled on read out. To read data the bit line halves are precharged to Vr, halfway between ground and V, by pulse #1 through transistors 30, 31, switches 21 remaining non-conductive throughout a read/write access. The appropriate word line 10, 24 is then selected and the appropriate bit line half is either grounded or raised towards V depending on the stored voltage. A subsequent pulse #2 actuates the latch which amplifies the potential difference between the bit line halves by raising the potential or bit line half 8 to V and lowering that on bit line half 16 to ground or vice versa depending on whether a binary 0 or 1 has been read. A subsequent read pulse gates the voltage on bit line output 33 as a read signal. To read a read only cell, pulse #1 initially grounds the read only bit line 20, switches 21 being closed at this time. A word line is then selected and switches 21 are rendered conductive so that if the selected cell has a gate the potential on bit line half 16, initially Vr, see above, is raised towards V whereas if the selected cell has no gate the potential or bit line half 16 falls towards ground. In either case the latch 11 amplifies the potential difference between the bit line halves 8, 16 and raises the potential on bit line half 16 to V and lowers that on but line half 8 to ground or vice versa depending on whether a binary 1 or 0 has been read.

Abstract: 858,206. Electric selective signalling systems. BROWN, BOVERI & CIE. A.G. Oct. 9, 1958 [Oct. 9, 1957], No. 32304/58. Class 40 (1). In a mine signalling system, Fig. 1, signalling from the cage 15 to the ground level winding control station is effected by varying the electrical transmission characteristics of the cable 1 carrying the cage. In a first embodiment, Fig. 1, by means of a switch in the cage, either a capacitor, or an inductance or both a capacitance and an inductance can be inserted in series in the cable loop. At the control unit the particular selection made in the cage is detected by inducing a current in the cable loop by a transformer 4 and coupling the current so introduced via a transformer 5 to a phase responsive device 7 which causes the contact of a polarised relay 9 to assume one of three positions corresponding to the position of the switch in the cage. The device 7 also receives the supply current via networks 13 and 14 to act as a reference phase. In a second embodiment at the cage, one of three resonant circuits resonant at different frequencies is inserted in series in the cable loop, and the particular circuit chosen is detected at the control unit by inducing the cable loop all three frequencies and detecting that one which is not substantially blocked. In a modification the circuits inserted in the cable loop at the cage can be done so inductively.
